gtp: Use for_each_netdev_rcu() in gtp_genl_dump_pdp().

[ Upstream commit 46841c7053 ]

gtp_newlink() links the gtp device to a list in dev_net(dev).

However, even after the gtp device is moved to another netns,
it stays on the list but should be invisible.

Let's use for_each_netdev_rcu() for netdev traversal in
gtp_genl_dump_pdp().

Note that gtp_dev_list is no longer used under RCU, so list
helpers are converted to the non-RCU variant.
